The invention has the beneficial effects as follows: adjust due to being respectively provided with welded tube v shape opening before and after high-frequency induction welding machine structure
Regulating device, postwelding pressurizing unit, solve and control difficulty to affect to weld because high-strength steel has the high least v shape angular aperture causing
The seam problem of quality and welded tube postwelding circularity is nonconforming or bonding place that may be present de- split problem so that high strength steel pipe,
Super-high strength steel pipe can be manufactured via Welded tube production mode.
Because postwelding pressurizing unit is when pipe is bonded at opening, by three pressure rollers from three directions to pipe
Extruded, thus both can guarantee that the degree of adhesion at opening, and can weld seam " Fructus Persicae is pointed " after effective control extruding it is ensured that pipe
Roundness, improve weldquality.Welded tube after three rollers extrude, immediately enter two rollers extruding, effectively prevent high-strength steel because
High least the de- of opening bonding place is caused to split it is ensured that the dimensional accuracy of welded tube diameter.
Because the upper guide roller assembly of welded tube v shape opening adjusting device and lower steering roll assembly are arranged on rotating seat,
Whole line has just been started shooting when just producing after producing or change production cast, can deflect situation according to the weld seam occurring in production, to rotate
Upper guide roller assembly and the position of lower steering roll assembly, are adjusted to position at circular tube open and reverse it is ensured that produce
Welded tube welding seam position do not glance off it is therefore prevented that weld seam deflection lead to inner and outer welding cannot continuous deburring phenomenon generation；
Lower steering roll assembly and upper guide roller assembly relative position are adjustable, according to unlike material, thickness strip steel, v shape can be opened
Bicker angle is adjusted, and is effectively controlled the stability of weld seam angular aperture, improves weld seam comprehensive quality；Further, since
Upper guide roller assembly and lower steering roll assembly can integrally be adjusted along before and after welded tube conveying direction with base plate, by adjusting upper guide roller
Distance between assembly and lower steering roll assembly entirety and front end welded tube cans device, makes welded tube v shape angular aperture angle
Size produces change, can be adjusted as needed, control the stability of weld seam angular aperture further.
Chiller due to this welded pipe units adopts postwelding air cooling+air-cooled+water-cooled compound mode, elongates weld seam and hot shadow
Ring area cool time, to avoid high-strength steel welded tube because of welding residual stress concentrations issuable cold crack, to improve
The obdurability of high-strength steel weld joint.
Because upper guide roller assembly can be provided with two installations along just moving to lower steering roll direction on described rotating seat relatively
Block, is provided with regulation notch in mounting blocks, be vertically equipped with adjusting screw rod by screw thread in mounting blocks, and tune is stretched in adjusting screw rod bottom
In section notch, adjust in notch and be provided with movable block, movable block is fixed on adjusting screw rod lower end, and described upper guide roller assembly is erected at
Between two movable blocks, during the tubing specification change processed, can be used for adjusting guide roller assembly, the position of lower steering roll assembly
Put so that the suitability of this device is wider.
Due to being vertically equipped with screw rod in stand, screw rod bottom is provided with mobile foundation, and described rotating seat is rotatably arranged on shifting
In moving base, described worm screw is also disposed on mobile foundation, can up-down adjustment guide roller assembly compacted position so that this device
More easy with the other equipment cooperation on welding production line；And can by upper shifting mobile foundation raise welded tube bottom line make to be welded
Tubular overarch, thus eliminate after v shape open region metal strip edge is drawn god during molding pipe produce undaform wrinkle
Pleat, is beneficial to the weld seam pairing welding of metal tape, improves the comprehensive quality after weld seam welding.
Because each sliding shoe is connected with corresponding leading screw by adapter sleeve in postwelding pressurizing unit, decreases this postwelding and squeeze
The processing of pressure device and installation difficulty.
Because pressure roller vertical in postwelding pressurizing unit includes two mounting blocks being oppositely arranged in upper sliding seat, wherein one
It is provided with adjusting set, adjusting set is provided with screwed hole, perpendicular roll shaft is provided with the screw thread being matched therewith, perpendicular roll shaft one in individual mounting blocks
End is located in other end activity in adjusting set and is located in another mounting blocks, perpendicular roll shaft rotates and is provided with roll body, adjustable vertical
To the position of pressure roller, vertical pressure roller is enable preferably to match with two horizontal pressure rollers.
